Numerical experiments on parameter estimation in acoustic media using the adjoint method

We present an algorithm to solve the problem of estimation of the wave speed in a layered acoustic medium. It is based on the adjoint method. Even though it is a fast algorithm, it is able to detect approximately the interfaces and estimate the amplitudes of the speed parameter. Numerical examples i...

Sumario:We present an algorithm to solve the problem of estimation of the wave speed in a layered acoustic medium. It is based on the adjoint method. Even though it is a fast algorithm, it is able to detect approximately the interfaces and estimate the amplitudes of the speed parameter. Numerical examples illustrate the application of the algorithm in seismic inversion.
